The goal: Build a digital harmonica (DH)
Reason: Does not exist in commercial market. Utilizes both signals and systems computer engineering cirriculum. We all enjoy music and think a handheld electronic instrument that can be played by mouth would be pretty cool! Harmonicas are not easily tuned, due to the mechanical complexity that comes with changing reeds that are in the harmonica chassis.
Key Specifications:
- The digital harmonica (DH) shall be able to send audio to an external speaker
- DH shall be able to play in multiple keys
- DH shall allow the user to move around freely while playing
- DH shall play 10 different notes per key
- DH shall weigh less than a pound
Tools and Technologies:
- Raspberry Pi
- SamplerBox
